WATER SYSTEM.

Application fi1ed March 12,

5 generally includes a pump cylinder located underground, a pump-piston reciprocating in the cylinder and a pump rod or plunger extending from the piston above the ground where the rod is attached toa reciprocating mechanism.

It is among the objects of this invention to provide improvements in the operating mechanism for a lift pump, and more'particularly to provide a self-contained unitary structure which may be readilyinstalled over a pump well, which is readily demountable for repairs and replacement of parts, and which includes a self-contained lubricating system.

A further object of the invention is to provide a unitary structure comprising pump operating mechanism, a storage tank, and an air pump connected therewith for maintaining the liquid within the tank under compression. 4

Other and further objects and advantages of the-present invention will be apparent from the. following description of one form of the invention, reference being made to the accompanyingdrawing.

In the drawings:

Fig.;1 is a side elevation, partly in section, of a pump operating unit constructed in accordance with the present invention;

and

Fig. 2 is an end view of thecompression tank and a sectional view of the pump operating mechanism, the section being taken on the line 22 of Fig. 1. v

, Referring to the drawings, the base is adapted to be mounted upon a suitable horizontal support located adjacent a well opening and its bottom wall 21 is provided with a circular opening through which extends a sleeve 22, having a circular flange 23 by means of which the sleeve 22 is supported by the bottom wall 21. Sleeve 22 is attached to a pipe 24 extending down adjacent the bottom of the well and providing there a cylinder 25 within which reciprocates a piston 26 provided with a valve 27. l Piston 26 is mounted on rod 28 attached by coupling 29 to the reduced end 30 of a rod 31. Rod 31 carries upon its )5 reduced end 30 a piston 32 which recip- 1923. Serial No. 624,324.

rocates within a cylinder 33 screw-threaded into a flange 34 which rests upon and fits within a suitable aperture provided in. the upper wall of rests upon the frame 35 The parts gether in and 35 are urovided with aligned central apertures larger in diameter than the rod 31 so as to provide a passage around the rod 31 of substantial dimensions. 35v is centrally apcrtured to receive therod 31 and carries a' stuffing box including packing 35 and a gland 35. j The frame 35 rests upon the valve frame 35 34, 35, and 35 are secured to-' is. provided with an air inlet passage 36,

inlet valve 37, outlet passage 38, and outlet valve 39'. Passage 38' communicates withair outlet pipe 40 attached to a storage tank 41. a The pipe 24 provides an intakepassage sleeve 22. A valve frame 35; flange 34 and a stufiing box any suitablemanner. Parts 34 g The frame for fluid into the sleeve 22, and the outlet from the sleeve 22 to the tank 41 includes the piping connections 42 with the check valve 43. I It is obvious that the upward movement of the rod 31and consequent upward movement of pistons'26 and 32 will cause liquid within the .pipe .24 to be lifted and forced through the piping 42 and check valve"43- into the tank 41." At the same time air conform "a part of the liquidpump serve also as the piston and cylinder of an air pump thus dispensing with \an additional cylinder and piston,

Pmnp operatmg meclaamsm.

The pump operating mechanism or driving-unit comprises a frame 50 attached by bolts 49' to the base 20. The frame 50- includes an oil reservoir 51 having-"a bottom wall 52 through which is provided an aperture 53 which is surrounded above the wall 52 by means of a flange 54 which is upwardly a tained in the cylinder 33 and above the that the piston 32 and cylinder 33 which i diverging as shown in Fig. 1. This flange 54 merges into a flange 55 surrounding the passage 53 below the wall 52 of oil reservoir 51. The side walls of flange 55 are parallel while the end walls thereof are partly downwardly converging and partly vertical as shown in Fig. 1.

The flange 55 supports a cross head guide 56 within which reciprocates a cross head 57 having threaded engagement with the pump rod 31. Cross head 57 sup-ports a wrist pin 58 passing through the lower bearing 59 in connecting rod 60 having an upper bearing 61 surrounding a crank62. Crank 62 is provided with crank shaft ends 63 and 64 mounted within bearings 65 and 66, re-

, spectively, which are secured by means of hearing caps 67 and 68, respectively, to opposite side walls 69 and 70, respectively, of the oil reservoir 51.

Upon the upper end of frame .50 and to provide a cover for the reservoir 51 and to provide a support for other operating mechanism, there is mounted a frame 71 supporting bearings 72 and 73 which are retained by means of plates 74 and 75, respectively.

Bearings 72 and 73 support a motor shaft 76 carrying at one end a motor rotating member not shown but housed within the motor field frame 77 which is attached by bolts 78 to the frame 71. The other end of the shaft 76 carries a flywheel 80 located within a flywheel housing 81 provided by the frame 71. Housing 81 is provided with a cover 82 attached by screws 83 to frame 71. As disclosed in our copending application S. N. 624,323, filed March 12, 1923, the motor rotor is mounted upon a sleeve detachably secured to the motor shaft. Removal of cover 82 permits access to housing 81 for the removal of flywheel 80 which is held in place by means of bolt 84. Removal of the motor frame 77 will expose the overhanging armature at the left end of shaft 76, then screws 85 can be removed to permit removal of the plate 74. After this is done the shaft 76 can be moved to the left and removed from the housing carrying with it a hearing 72, an oil thrower 86, and the sleeve v87 on which the motor rotor is secured.

Shaft 76 is provided with a worm 90 which drives a worm gear 91 attached to the crank shaft 64. It is obvious that ro tation of the motor will produce reciprocation of-the pump rod 31. That portion of the pump rod 31 which is included between the cross head 57 and the stuffing box frame 35 is enclosed by a sleeve 95 which is held in position by a screw 96 bearing against the cross head guide 56. If it should be necessary to obtain access to the pump rod 31 to disconnect it from the cross head 57 thevscrew 96 can be remove-d, the sleeve 95 elevated to the dotted line position 95, and the screw 96 inserted in a tap hole 97 as shown at 96, whereby to hold the sleeve 95 in upper position.

' Lubrication of the mechanismis effected in a simple manner by a splash system. A quantity of lubricant is introduced by a filler 100 in a reservoir 51 provided by the frame 50. The height of the vertical leg of the ell of filler 100 determines the lubricant level 101 and therefore the desired amount of lubricating oil necessary for the proper lubrication of the system. The gear 91 will splash oil from the reservoir into the upper part of the housing 71. Some of this oil will be splashed into the bearings 72 and 73 and the excess will be returned to the reservoir 51 some through the flywheel housing 81 and some oil returning through the return channel 102 provided in the plate 7 4 for draining the oil catching groove 103. The bearing caps 67 and 68 (see Fig. 2) are provided with pockets 105 and 106, respectively, for receiving lubricant splashed by the gear 91. The crank 62 is walled off from the zone of splash lubrication by means of a wall 54 extending upwardly from one of the vertical walls of the flange 54. A duct 107 bridges the space directly over the crank 62 for conducting oil from the oil splashing zone over to the bearing cap 67 and bearing '65. Some of the excess oil on the crank shaft parts 63 and 64 will find its way to hearing 61, down the connecting rod 60 to the wrist pin 58 and down the surfaces of the cross head guide 56. Since the lubricating oil is sparingly distributed to the crank 62 there will be little or no oil dripping from the lower edge of the cross head guide 56. Most of the excess will be consumed by the reciprocating parts of the pump driving mechanism. Any oil which may collect in the sleeve 95 will leak out of the machine without entering the water passages.

The frame 71 and parts supported thereby can be assembled as a unit before assembling on the frame 50, and likewise this unit may be removed without first disassembling any part of it. By removing the screws 110 and the bearing cover 111,-and the screw 112, the frame 71 and mechanism supported thereby may be lifted and removed from the rest of the driving mechanism.

If it is desired to make the plant automatic a pressure operating switch contained within the housing is mounted upon the frame 71. The details ofthis switch are disclosed in the copending application of Charles F. Kettering and George A Buvinger, Serial No. 299,195, filed May 23, 1919. Therefore, for the understanding of this invention it is sufficient to state that the controller 120 comprises a diaphragm box 121 having a flexible side wall connected with motor switch mechanism there being a pipe 122 connecting the tank 41 with the dialei-voir supported above the base and phragm box. When the pressure in tank 41 falls below a certain amount the pressure in the diaphragm box 121 will be released permitting a spring mechanism to close the motor switch. After the pressure has been built up in the tank 41 by pumping water into it, this pressure when great enough will cause the motor switch to open and stop the pump mechanism.

The pressure storage tank 41 is mounted upon the frame by means of brackets 130 and straps 131, and the tank is equipped With the usual water lever sight glass 132,

pressure gauge 133, and release valve 134 attached to the tank outlet 135.

The reservoir 51 and cover 71 provide a gear case for the transmission gearing from the motor 77 to the crank shaft 64. The flanges 54 and 55 onthe bottom wall of reservoir 51 and the cross head guide 56 provide an enclosure for the operating parts extendin outside the reservolr. That portion of t e pump rod '31 between the pump and the cross head is enclosed by the removable sleeve 95. In this manner all parts of the operating mechanism and the pump rod above the pump are enclosed and protected and also lubricated by a system of splash lubrication contained in the gear case members 51 and 71. Removal of cover 71 can be accomplished without disturbing the crank shaft and the operating mechanism supported by cover 71 is removable therewith as a unit. The crank shaft, connecting rod and cross head can then be removed in assembled relation after the cross head has been disconnected from the pump rod. The frame and operating mechanism can be removed as a unit from the pump without disturbing the pump and supporting base 20.

While the form of mechanism herein shown and described constitutes a preferred embodiment of one form of invention, it is to be understood that other forms might be adopted and various changes and alterations made in the shape, size, and proportion of the elements therein without departing from the spirit and scope of the invention.
